I can only compare TB ALC with Viscaria. Overall I felt that the Vis had SLIGHTLY more feel and stability while the TB ALC was slightly faster, stiffer and spinnier. Some notes to consider is that Viscaria has better rubber synergy as it works well with all rubbers including Chinese rubbers but TB felt weird if using Chinese rubbers and very very soft euro jap rubbers. I also noticed that when far away from the table, the TB ALC started to lose power and the user has to put much more effort just to get the ball over the net while the Viscaria did not have this problem, do note that this could be due to differences in the blade and not the model as 2 blades of the same model will play differently. But irregardless, both blades are good and you would do well with either one. If I must choose, I would choose the Vis purely for the extra feel which is quite significant, also the better rubber synergy helps if you decide to switch to different rubbers in the future for whatever reasons. You could also look into the new innerforce layer ALC, Ive read and heard some good things about it.
